This math professor has a whole section On Writing on his website. A couple of my favorites:
his excellent idea for “rapid prototyping” method applied to writing papers (not exactly sure what this means but I like it). This seems particularly valuable for those of you who voiced frustration and how long it takes you to write.
This math professor is also excellent. (Probably at math, too, but all I care about is his interest in communicating technical concepts in clear language.) He came up with the “three things” exercise. He has another really cool thing: a list he maintains of great writing on math. Can you think of examples of great writing about engineering, or in your subdiscipline?
